# IF vs PFC

The clearest difference is in-app purchases: PFC at none against IF's 10. PFC also leads on ads (none vs shown) and update cadence (every 10 days vs every 3 weeks). IF's advantage is device support (4 vs 2). On price and iOS requirement there is nothing between them.

Both are free to download. IF sells 10 in-app purchases, starting at $9.99 per month. PFC asks for nothing beyond the download.

IF ships an update every 3 weeks, PFC every 10 days. The most recent releases landed on November 6, 2026 and October 31, 2026 respectively.
